Hi there Mehmet,

I couldn't find the blog post that has the issue, so I created my own test post and it works fine as shown here http://screencast.com/t/vFeR1Rsvy

I believe the issue could be that you embedded an image from the media gallery, and then the image is removed. I've tested this as shown here: http://screencast.com/t/h7SvYIEe

I hope this helps!
